In 2012, Critical Systems Labs (UK) Ltd. provided consulting services to ITER in the support of its approach to machine protection for the world's largest experimental tokamak nuclear fusion reactor under development in southern France. In addition to helping specify the functional requirements for the magnet interlock system, we examined the inter-dependencies between major systems associated with the magnet interlock system and other elements of the central interlock system.

Among other benefits, this work lead to the refinements to interfaces between the magnet interlock system and other system which are needed to properly manage different patterns of system behaviour when discharging the powerful magnets responsible for confining the plasma in the reactor vessel.
